F21 Error Code Meaning
The Maytag washer F21 error code points to a water drainage problem. This code appears on the display when the washer cannot drain water properly. Understanding this error code helps fix the issue faster.
Water must drain out for the washing cycle to complete. The F21 code means the washer detects water still inside after the drain cycle. It stops the wash to avoid flooding or damage.

Basic Checks Before Repair
Before starting any repair on your Maytag washer showing the F21 error code, some basic checks save time and effort. These simple steps help find easy fixes and avoid unnecessary repairs.
Checking power, water, and door lock can often solve the problem. These parts play a key role in your washer’s normal operation.
Power Cycle The Washer
Turn off the washer and unplug it from the power outlet. Wait for one minute. Plug it back in and turn it on. This resets the washer’s computer. Sometimes, this clears error codes like F21.
Inspect Water Supply
Look at the water hoses connected to the washer. Make sure they are not bent or blocked. Check if the water faucets are fully open. Proper water flow is necessary for the washer to work correctly.
Check Door Lock
Open and close the washer door firmly. The door must latch tightly. A loose or faulty door lock can cause the F21 error. If the door does not lock properly, the washer will not start the cycle.
Troubleshooting Drainage Issues
Drainage problems often cause the Maytag washer to show code F21. This error means the washer cannot drain water properly. Fixing drainage issues can get the washer back to work fast. Simple steps can clear common blockages and pump problems. Follow these tips to troubleshoot drainage issues easily.
Clean The Drain Pump Filter
The drain pump filter can catch lint and small objects. A clogged filter stops water from flowing out. Find the filter access panel on the washer. Open it carefully and place a towel below. Remove the filter and clean out any debris inside. Rinse the filter with water to clear all dirt. Put the filter back firmly before closing the panel. This quick step often fixes drainage errors.
Clear Blocked Drain Hose
The drain hose carries water from the washer to the drain. Sometimes it bends or gets clogged with dirt. Check the hose for kinks or sharp bends. Detach the hose from the washer and the drain pipe. Use a long brush or running water to clear any blockages. Reattach the hose securely to avoid leaks. Clear hoses help water drain smoothly and stop error codes.
Test The Drain Pump
The drain pump moves water out of the washer. A faulty pump can cause drainage problems. Listen for strange noises during the drain cycle. Unplug the washer and remove the pump from the unit. Check the pump for damage or stuck parts. Use a multimeter to test the pump’s electrical function. Replace the pump if it fails the test. A working pump ensures proper drainage and stops F21 errors.
Inspecting And Replacing Parts
Inspecting and replacing parts is a key step in fixing the Maytag Washer Code F21 error. This code often points to problems with water flow or pressure inside the machine. Checking parts carefully helps find the exact cause. Fixing or replacing broken parts can stop the error from showing again.
Always start with the simplest checks. Use basic tools and be cautious with electrical parts. Safety first. Some parts wear out over time and need replacement to keep the washer working well.
Examine Water Inlet Valve
The water inlet valve controls water entering the washer. If it is blocked or broken, water flow can stop. Look for clogs or damage on the valve. Clean any dirt or debris from the screen. Use a multimeter to test if the valve gets power. Replace the valve if it does not open properly.
Check Pressure Switch
The pressure switch senses water level inside the washer. A faulty switch can cause the F21 error. Remove the switch and check its hose for cracks or blockages. Test the switch with a multimeter for continuity. Replace the switch if it shows no response or damage.
When To Call A Technician
Some repairs need expert tools and skills. Call a technician if you cannot find the problem. If replacing parts does not fix the error, professional help is best. Avoid risking injury or causing more damage. A technician can diagnose and repair complex issues safely.
Preventing Future F21 Errors
Preventing future F21 errors on your Maytag washer helps save time and money. Regular care keeps the machine running smoothly. Simple steps reduce the chance of this error showing up again.
Regular Maintenance Tips
Clean the washer drum and detergent dispenser often. Remove dirt and residue to avoid clogs. Check hoses for cracks or leaks every few months. Replace worn parts quickly to stop damage. Run a cleaning cycle with vinegar or washer cleaner monthly. Keep the area around the washer dry and free of dust.
Proper Loading Practices
Do not overload the washer. Too many clothes strain the motor and sensors. Spread clothes evenly inside the drum. Balance heavy items with lighter ones. Use the right amount of detergent for your load size. Overuse of soap can cause buildup and errors. Follow the washer’s load guidelines in the manual. This helps the machine work well and last longer.
